Based upon my experience working on the 59.F0 issue, I recommend trying the firmware upgrade to see if it resolves the error before replacing anymore parts.
A few questions regarding the 59.F0 Error occurrence on your printer:
- Is the error clearable by power cycle?
- If so, do you have any ideas what happens just prior to the error re-occurring?
- How many pages are on your printer?
- Is your printer still covered under the 1-year warranty?
Please respond with the results of the firmware upgrade and the answers to the questions above and I can be of more assistance if the issue is still not resolved.
